Oxygen is absorped into the blood by the process of diffusion. A large surface area, short diffusion pathway (the distance the oxygen has to travel through) and large concentration gradient increases the ...

First, we start by moving the x's all over to one side. These are our undefined variable and it is important to keep them together. To do this, we take away 3x from either side and we get:

3x - 3 &...

This is the force that resists movement between two surfaces which are in contact.

Extensive root systems allow for maximum uptake of available water from the ground. Low surface area to volume ratio reduces the rate of evapotranspiration, alongside a thick waxy cuticle covering the sur...

Example of an alkane is C_{​​​​​​}H_​4​​​​ methane

The main difference between alkane and alkene is the saturation of the carbon-carbon bond. In alkane is unsaturated and has a C-...
